Codes P0236 et P0237 sur S80 2002

Bonjour,

En faisant un scan sur une S80 2002 T6, j'ai eu deux codes :

• P0236 - Turbocharger Boost Sensor 1 Performance
• P0237 - Turbocharger Boost Sensor 1 Circuit Low Voltage

Je veux simplement savoir à quoi m'attendre pour régler ce problème : dans le meilleur des cas et dans le pire des cas. Exemple, dans le meilleur des cas c'est nettoyer pour que le sensor soit correcte ? et dans le pire des cas c'est changer le turbocompresseur fautif ?

Merci pour votre aide !

P0236 = ECM-170F Atmospheric pressure sensor/boost pressure sensor range check. Faulty signal. Intermittent fault, B6294T
Print

Diagnostic trouble code (DTC) information

Condition
Diagnostic trouble code (DTC) ECM-170F is stored if the boost pressure sensor's registered pressure deviates from the atmospheric pressure sensor's registered pressure. This comparison is made at engine start (at approximately 500 rpm) before the turbocharger (TC) has built up a boost pressure.

Substitute value
Possible source
Faulty signal
contact resistance in terminals
defective boost pressure sensor
defective atmospheric pressure sensor

Fault symptom[s]
none

P0237 - ECM-1600 Boost pressure sensor. Faulty signal, B6294T
Print

Diagnostic trouble code (DTC) information

Condition
Diagnostic trouble code (DTC) ECM-1600 (signal too high or too low) is stored if the signal from the boost pressure sensor is outside its normal range. The fault is diagnosed by the control module when the ignition is on / the engine is running.
Diagnostic trouble code (DTC) ECM-1600 (faulty signal) is stored if the signal from the boost pressure sensor is within its normal range but deviates from the calculated boost pressure. The fault is diagnosed by the control module when the engine is running.

Substitute value
Limited boost pressure (if the signal is too high).
Possible source
Signal too high:
Contact resistance in the terminals
Short-circuit to supply voltage in the signal cable
Open-circuit in the signal cable
Defective boost pressure sensor.
Signal too low:
Short-circuit to ground in the signal cable
Defective boost pressure sensor.
Faulty signal:
The boost pressure sensor has come loose
Contact resistance in the terminals
Defective boost pressure sensor.

Fault symptom[s]
Malfunction indicator lamp (MIL) lit
Poor performance.

Merci pour les infos, mais ça me dit rien sur ce qui « pourrait » être à faire pour régler le problème. Des idées ?

Merci !
